Definitions
- the present invention relates generally to lithography, and more particularly, to an apparatus and method for compensating for pressure exerted on the lithography lens caused by the immersion fluid.
- a lithography apparatus is used to transfer images defined by a reticle or other patterning element such as a programmable mirror array (see US Patents
- a typical lithography apparatus includes an illumination source, a reticle stage assembly for positioning the reticle, a wafer stage for supporting the wafer, and an optical assembly including lenses for projecting the image defined by the reticle onto the wafer.
- Control and measurement systems are also provided to control the movement of the wafer and measure the position of the wafer relative to the optical assembly respectively.
- Immersion lithography systems utilize a layer of immersion fluid that fills a gap between the final lens of the optical assembly and the wafer.
- the fluid enhances the resolution of the system by enabling exposures with numerical apertures (NA) greater than one, which is the theoretical limit for conventional "dry" lithography.
- NA numerical apertures
- the fluid in the gap permits the exposure with light that would otherwise be totally internally reflected at the optical-air interface.
- numerical apertures as high as the index of refraction of the immersion fluid are possible.
- Fluid immersion also increases the depth of focus, which is the tolerable error in the vertical position of the wafer, compared to a conventional lithography system.
- Immersion lithography thus has the capability of providing resolution down to 50 nanometers or lower.
- fluid pressure on the lens may cause the last lens of the optical assembly to become displaced. More specifically, the amount of force on the lens depends on the pressure exerted by the fluid and the size of the surface area of the lens, lens mount hardware, and any immersion fluid supply nozzles attached to the lens mount hardware.
- the fluid pressure may be caused by a number of reasons. With immersion lithography, the surface tension of the liquid at the air-fluid interface surrounding the exposure area, sometimes referred to as the meniscus, has the effect of sucking or pulling down the lens and optical assembly. Variations in the amount of immersion fluid may also cause pressure variations on the lens. The applicants have found that a positive or negative change of only 0.02 cubic centimeters will cause a change of force of approximately 50 milli-newtons on the lens with an 80 millimeter diameter. Also as water escapes the gap, the water flow also has a tendency to create a pull down force on the lens. Dynamic motion of the wafer in the horizontal plane can cause shear forces that exert pressure on the lens.
- An apparatus and method for compensating for pressure exerted on the lithography lens caused by the immersion fluid is therefore needed.
- the present invention is related to an immersion lithography system that compensating for any displacement of the optical caused by the immersion fluid.
- the system includes an optical assembly to project an image defined by the reticle onto the wafer.
- the optical assembly includes a final optical element spaced from the wafer by a gap.
- An immersion element is provided to supply an immersion fluid into the gap and to recover any immersion fluid that escapes the gap.
- a fluid compensation system is provided to compensate for the force on the final optical element of the optical assembly caused by pressure variations of the immersion fluid to minimize the displacement of the final optical element. The resulting force created by the varying pressure may cause final optical element to become displaced.
- the fluid compensation system is configured to provide a substantially equal, but opposite force on the optical assembly, to prevent the displacement of the final optical element.

- Figures 6A and 6B are flow diagrams illustrating the fabrication of semiconductor devices using the immersion apparatus of the present invention.
- Figures 7A and 7B are diagrams of a fluid pressure compensation system for an immersion lithography according to another embodiment of the invention.
- the immersion apparatus 10 includes a reticle stage 12, an optical assembly 14 including a final optical element 16, and a wafer stage 18 for supporting a wafer 20.
- An immersion device 22, sometimes referred to as a nozzle, is positioned between the final optical element 16 and the wafer 20 on the wafer stage 18.
- the immersion device is responsible for supplying fluid into the gap 24 between the final optical element 16 and the wafer 20.
- the immersion device is also responsible for recovering immersion fluid that escapes the gap 24.
- the immersion fluid may be a liquid such as water or oil.
- FIG. 2 an enlarged cross-section view of a fluid pressure compensation system for an immersion lithography apparatus according to one embodiment of the invention is shown.
- the apparatus 10 includes a lens mount 32 used to mount the final optical element 16 to the optical assembly 14.
- the final optical element 16 is positioned over the wafer 20.
- the immersion device 22 (not shown for the sake of simplicity in Figure 2) is responsible for providing and recovering immersion fluid 34 from the gap 24.
- a meniscus 35 of immersion fluid is created at the fluid-atmosphere interface below the outer-edge of the lens mount 32.
- a fluid compensation system 36 is provided to compensate for any changes in the force on the final optical element 16 caused by changes in the pressure of fluid 34.
- the fluid compensation system 36 includes a chamber 38 that surrounds the last optical element 16 and is positioned between the optical assembly 14 and the lens mount 32.
- the chamber is filled with immersion fluid 34.
- Passages 40 fluidly couple the immersion fluid 34 in the gap 24 with the chamber 38.
- a purge device 44 is fluidity coupled to the chamber 38 through a passage 42.
- the chamber 38 is generically characterized as a device that is capable of expanding or contracting in the vertical direction but not in the horizontal direction.
- the chamber 38 may be a bellows, piston, diaphram, or other passive pressure responsive device.
- the passages 40 and 42 may be a duct or other opening fluidly connecting the immersion fluid 34 in the gap with the chamber 38 and purge device 44.
- changes in the pressure of the immersion fluid 34 may create forces on the final optical element 16, the lens mount 32, and the immersion device, all of which may result in displacement of the final optical element 16.
- the chamber 38 is designed to create an equal but opposite force to compensate or cancel out the force created by the immersion fluid 34.
- pressure caused by the immersion fluid 34 in the gap 24 increases, an upward force is created on the final optical element 16.
- the increased pressure concurrently causes a corresponding increase in the pressure in the chamber 38 via the passages 40.
- the increased pressure results in the expansion of the chamber 38, creating an equal but opposite downward force on the lens mount 32.
- the final optical element 16 is not displaced.
- the pressure of the immersion fluid 34 decreases in the gap 24 a downward force on the final optical element 16 is created.
- the decreased pressure results in a corresponding decrease in pressure in the chamber 38. Consequently, the chamber 38 compresses, causing an equal but opposite upward force on the lens mount 32.
- the final optical element 16 is not displaced.
- the horizontal surface area of the top and bottom surfaces of the lens mount 32 in contact with the chamber 38 and immersion fluid 34 are substantially the same.
- the substantially equal surface area ensures that the chamber 38 exerts an equal but opposite force on the top surface of the lens mount 32 as the immersion fluid 34 exerts on the bottom surface of the mount 32 and the final optical element 16 combination.
- the bottom surface of the lens mount 32 has a radius Ri and the inner and the optical assembly 14 has an outer and inner radius R2 and R3 respectively.
- the lens mount 32 and the optical assembly 14 are round, this shape should not be construed as limiting the present invention.
- the lens mount 32 and optical assembly 14 can be any shape, including but not limited to square, rectangular, oval, etc.
- the equal but opposite forces on the bottom and top surfaces of the lens and lens mount are substantially vertically aligned.
- the apparatus 50 includes a lens mount 32 used to mount the final optical element 16 to the optical assembly 14.
- the final optical element 16 is positioned over the wafer 20.
- the immersion device 22 (again not shown for the sake of simplicity in Figure 3) is responsible for providing and recovering immersion fluid 34 from the gap 24.
- a meniscus 35 of immersion fluid is created at the fluid-atmosphere interface below the outer-edge of the lens mount 32.
- a fluid compensation system 52 is provided to compensate for any changes in the force on the final optical element 16 caused by changes in the pressure of fluid 34.
- the fluid compensation system 52 includes a pair of actuators 54 mechanically coupled between the lens mount 32 and the sidewalls of the optical assembly 14.
- Optical position sensors 56 mounted on struts 58 that extend from the sidewalls of the optical assembly, are provided to measure the relative position of the lens mount 32 with respect to the optical assembly 14.
- a pressure sensor 60 is used to measure the pressure of the immersion fluid 34 in the gap 24.
- a control system 62 coupled to both the pressure sensor 60 and the position sensors 56, is used to control the actuators 54.
- the immersion fluid 34 may become pressurized, either positively or negatively, for the reasons described above.
- This pressure is applied to the bottom surface of the lens mount 32, last optical element 16, and the nozzle, all of which may contribute to the displacement of the final optical element 16.
- Pressure variations of the immersion fluid 34 are continuously provided to the control system 62 as measured by the pressure sensor 60.
- the position sensors 56 also measure the actual position of the lens mount 32.
- the control system 62 in turn controls the actuators in real time to compensate for any displacement of the final optical element 16 caused by changes in pressure and detected by the position sensors 56. For example, when an increase in pressure causes the final optical element to be displaced upward, the control system 62 directs the actuators to exert an equal but opposite downward force on the lens mount 32.
- control system 62 causes the actuators 54 to exert an upward force on the lens mount 32 when the sensor 60 measures a decrease in immersion fluid 34 pressure. In either case, the actuators 54 prevent the displacement of the final optical element 16.
- control system 62 may use inputs from the position sensors 56 and the pressure sensor 60 to control the actuators. Alternatively, the control system may use inputs from either the position sensors 56 or the pressure sensor 60, but not both.
- the actuators may be internal to the lens mount 32, as opposed to being mechanically coupled between the lens mount 32 and the optical assembly 14. Referring to Figure 4, an enlarged diagram of the optical assembly 14 is shown. In one embodiment, kinematic clamps 70 are used to clamp the final optical element 16 to lens barrels 72 of the optical assembly 14.
- FIG. 5A a top view of the final optical element 16 is shown.
- the optical element includes a lens portion 16a and a flanged portion 16b extending around the periphery of the optical element 16.
- FIG. 5B a cross section view of the final optical element 16 and a clamp 70 is shown.
- the clamp 70 is configured to clamp onto the flanged portion 16b of the final optical element 16 to hold it in place within the optical assembly 14.
- the clamp 70 is described herein as a kinematic clamp, it should be noted that any type of mechanical clamp may be used.
- glue may be used to secure the final optical element 16 to the barrels 72 of the optical assembly 14. For the sake of simplicity, only one clamp 70 is shown.
- clamps 70 typically two, three or even more clamps 70 may be used around the circumference of the final optical element 16.
- separate or non-clamp actuators can be used to compensate for any displacement of the final optical element 16, similar to as illustrated in the diagram of Figure 3.
- the clamps 70 are the force actuators and are responsible for both holding the final optical element 16 in place within the optical assembly 14 and for providing the equal but opposite force to compensate for any displacement caused by the immersion fluid, similar to the actuators 54 of Figure 3.
- the force actuators may be VCMs, El cores, a low stiffness piezo stack, piezo bi-morph, or other magnetic or pressure driven actuators. Regardless of the type of force actuator used, the force applied by the clamps 70 to the kinematic mount should be equal to but opposite the direction of the force created by the immersion fluid 34. Furthermore, the forces created by each mount can be controlled by the control system 62 so that the center of the effort coincides with center of the fluid force.
- the control system 62 relies on both an actual instantaneous force calculation as measured by the pressure sensors 60 and position feedback as measured by the optical position sensors 56.
- the instantaneous force is calculated by multiplying the instantaneous pressure times the surface area of the final optical element 16, lens mount 32, and immersion element 22 in contact with the immersion fluid.
- An instantaneous counter-force can then be applied based on the outcome of the calculation.
- the position sensors 61 can be used for feedback to adjust the counter-force as necessary.
- control system 62 may rely on either the instantaneous force calculation as measured by the pressure sensors 60 (i.e., an open loop system) or the position feedback as measured by the optical position sensors 56 (i.e., a closed loop system), but not both. .
